IMG_1342.JPGAs the end of the year approaches, everyone seems to be making their lists. And, today, comes another one — U.S. states ranked for “clean energy leadership.”

Not surprisingly, California took the No. 1 spot, followed by Oregon, Massachusetts, Washington and Colorado. The bottom half of the Top 10 are New York, Illinois, Connecticut, Minnesota and New Jersey.

Clean Edge, a West Coast research and consulting firm, compiled the list based on 80 indicators, including a state’s renewable energy production, transportation systems, regulatory policies and incentives and financial and intellectual capital.

“We track more than 4,000 public and private data points across all 50 states,” said Ron Pernick, Clean Edge’s managing director.

The firm looked at such factors as patents for clean energy technology, electric car charging stations, green MBA programs and membership in regional climate initiatives.
